The rotary engine had financial advantages to Japanese consumers in that the engine displacement remained below 1,500 cc (1.5 L), a significant determination when paying the Japanese annual road tax this kept the obligation affordable to most buyers while having more power than the traditional engines having a straight cylinder configuration. In Japan, sales were enhanced by the fact that the RX-7 complied with the Japanese Government dimension regulations, and Japanese buyers were not liable for yearly taxes for driving a larger car. The advantage the RX-7 had was its minimal size and weight, and the compact rotary engine installed behind the front axle helped balance the front and rear weight distribution, which provided a low center of gravity. The transition of the Savanna to a sports car appearance reflected products from other Japanese manufacturers. The lead designer at Mazda was Matasaburo Maeda ( 前田 又三郎, Maeda Matasaburō), whose son, Ikuo, would go on to design the Mazda2 and the RX-7's successor, the RX-8.
In Japan it was introduced in March 1978, replacing the Savanna RX-3, and joined Mazda's only other remaining rotary engine-powered products, called the Cosmo which was a two-door luxury coupé, and the Luce luxury sedan. Mazda's internal project number for what was to become the RX-7 was X605.
